In this paper, different destruction forms of spatial grid structure are analyzed based on LS-DYNA. The key members of structure are studied and the collapsing processes of spatial grid structure caused by different failure members are simulated numerically. By comparing the results of numerical analysis, divisional design method is proposed based on the alternate path method (AP method). The divisional design method can improve resistance to progressive collapse obviously and is of certain reference value for engineering.
